Discoloration of Titanium Anodizing when touched

2007

I get a problem about discoloration after Titanium anodizing.
If people touch the object, the color is going to dimmer than it before touch.
Afterwards, cleaning this object can recover the color.
Could someone provide me some suggestions?

The dimmer spot sounds like finger print to me. Do you wear gloves while handling the parts?
